Abstract: 557,201. Combined greenhouse and dwelling. NODEN, T. J. July 31, 1942, No. 10714. [Class 20 (i)] A dwelling house is provided with an attic space which is covered with glass to form a greenhouse the floor of the attic being made waterproof. The walls 1 are provided with extensions 2 surmounted by a glass roof 3 forming an attic space above a waterproofed reinforced concrete floor 5 on which earth or boxes of earth may rest. The flues 6 of the various fireplaces pass through this space where they are formed of ribbed or finned metal plates to radiate heat and the ventilation is controlled by thermostats. On one side the floor extends to a verandah provided with trapped gullies to take away surplus water. In central heated and hot water heating systems for the house, radiators and the hot water cylinder may be included in the attic space as may also the cold water cistern from which water may be drawn to water the plants.

Title: Improvements in or relating to circuits for operating alternators in series
IPC: H02P1/54
Filed: 1956-04-10
Abstract: 812,937. Running generators in series. BROWN, BOVERI & CO. Ltd. April 10, 1956 [April 14, 1955], No. 10889/56. Class 38 (4). A circuit for running two medium-frequency generators in series comprises an auto transformer T, Fig. 1, having a tap A. Generators G1, G2 are connected across parts of the windings W1, W2, respectively, and the load B is connected across the whole winding. The auto transformer inductively couples the two generators so that a synchronizing current flows when the machines are not in synchronism. When the latter condition is achieved, the transformer merely acts as a choke across the load. A similar circuit is given for three generators in Fig. 2 (not shown). An arrangement for variation of output voltage by end taps on the winding is also described.

Abstract: 937,611. Electronic counting - apparatus. RACAL ELECTRONICS Ltd. March 31, 1960 [April 1, 1959], No. 11010/59. Drawings to Specification. Class 106 (1). In a reversible electronic counter, means are provided for determining whether the member registered therein is positive, negative or zero. As described, series of alternate " add " and " subtract " check pulses are supplied to an n stage decimal counter at times different from the pulses to be counted and the state of the highest decimal order is observed. The n stage counter is restricted to a capacity Œ 10<SP>n-1</SP>-1, negative numbers being registered in complement form and according as highest order remains at " 0 " or " 9," the number registered is positive or negative. If the highest order changes repeatedly at the check pulse frequency between " 9 " and " 0," the number registered in the counter is zero. The highest order may be connected to a flip-flop, the changing state of this when zero is registered in the counter being detected by a differentiating and integrating circuit. The invention is particularly applicable to counters employing ferrite cores.

Stamping.-A method for imparting the final form to tubular elbows, e.g. super-heater bends, by means of a punch and half dies is characterized in that the elbow is evenly heated and supported during the forming operation on the inside portion of the bend by the half-dies whereas the whole of the outside portions of the bend and of the straight legs respectively of the elbow are engaged by a punch slidingly received between the half-dies so that at the end of said sliding movement the said portions of the elbow are surrounded by the punch and the half-dies. The elbow a is placed between two half-dies b<SP>1</SP>, b<SP>2</SP>, each having a projection c<SP>1</SP>, c<SP>2</SP> together forming the crutch of the elbow said half-dies also being hollowed out to form semi-circular grooves AB, CD for forming the inside bend of the elbow.

Abstract: 559,916. Gas producers. FEHLING, H. R., and ROSIN, P. O. Aug. 12, 1942, No. 11301. [Class 55 (i)] The air and steam supplied to a gas producer are preheated to a temperature of about or higher than the minimum reaction temperature of the fuel, this temperature being between 700‹ and 1000‹ C., the proportion of steam to air being the maximum convertible into gas. A superheater having an efficiency of 75 per cent is stated to ensure automatic control of the temperature of the air and steam according to the producer load. Coal dust, tar or pitch may be gasified in the space above the fuel. A pair of down-draught producers 1, 2 with upward fuel feed are described, the retaining walls opening into a common supply space 7 for air and steam which pass downwards through the fuel beds to an outlet 8, a passage 9 being provided in the common wall 5. The fuel is fed upwards by screws 11 mounted on conical members 13. The heat exchangers 17 each have two vertical banks of tubes through which waste hot gases or other preheating gases pass and around which the air and steam circulate before they enter the space 7 by conduits 16. Apertures 22 are for the supply of coal dust, tar or pitch. Ash is discharged by a pusher 26 into an ashpit 29 which may be used as a secondary combustion zone. The damper controlling the heating gases to the superheater may be controlled by a thermostat to give the required temperature of the air and steam.
